Research Program Term. Except as otherwise provided herein, the term of the Research Program (“Research Program Term”) shall commence on the Effective Date and, unless otherwise terminated in accordance with the terms of this Agreement, shall continue until completion of the last to be completed or terminated Research Plan; provided that Pfizer agrees

Materials Transfer. In order to facilitate the Research Program, either Party may provide to the other Party certain materials for use by the other Party in furtherance of the Research Program. Neither Party may furnish any such materials to the other Party except as expressly provided in the applicable Research Plan or this Agreement without the prior written consent of the other Party. All such materials shall be considered the Information of the Party providing such material (provided that if they are a combination of the proprietary materials of both Parties, they shall be deemed the Information of both Parties) and shall be used by the receiving Party in accordance with the terms and conditions of this Agreement solely for purposes of exercising its rights and performing its obligations under this Agreement. All such materials must be used with prudence and appropriate caution in any experimental work, since all of their characteristics may not be known, and in compliance with all applicable Laws and any relevant Third Party contractual requirements that have been communicated in writing to the receiving Party. Such transfer will not be deemed a transfer of any intellectual property rights with respect to such material. Any and all compounds, biological materials, reagents, assays and other materials that are provided by one Party to the other Party hereunder in furtherance of the Research Program activities and that are not consumed in the course of performance of such activities, shall all be returned to the providing Party promptly upon the completion of the Research Program, or, if the providing Party so instructs in writing, or if such material exists in the form of a combination of the proprietary materials of both Parties, all such materials shall be destroyed and the destruction of such materials shall be certified in writing, in accordance with written instructions to be provided by the providing Party upon completion of the Research Program; provided, however, that such obligation shall not apply to the extent rights to the relevant materials or information are obtained or retained by either Party pursuant to the express provisions of this Agreement.

Exclusive Efforts. During the term of this Agreement, for so long as a Target is included in a license granted under this Agreement, and excluding the activities being conducted under the Research Program, Arvinas and its Affiliates shall not, either directly or indirectly (including on behalf of a Third Party), (i) conduct or agree to conduct any activities with respect to the Development or Commercialization of any pharmacologically-active agent whose primary mechanism of action is, by design, directed to such Target, or (ii) grant any license or covenant not to ▇▇▇ or other right to any Third Party with respect to the conduct of any such activities. Notwithstanding the foregoing, in the event that a Person that becomes an Arvinas Affiliate through a Change of Control or through acquisition of “control” (as defined in the definition of Affiliate) by Arvinas (a “Transaction”), has a program underway, at the time that Arvinas first enters into the Transaction, with respect to the Development or Commercialization of any pharmacologically-active agent whose primary mechanism of action is, by design, directed to such Target, such activity may continue following the effective date of the Transaction, provided that (i) such program is conducted by individuals who have (and have had) no involvement in the Research Program and no direct knowledge of or access to the Compounds, and (ii) such program does not utilize any Arvinas Information and Inventions, Arvinas Patent Rights, Arvinas Technology or Arvinas Technology Improvements.

Compliance with Law and Ethical Business Practices. Each Party shall conduct the activities of the Research Program and its other activities under this Agreement in accordance with all applicable Laws and good business ethics. Each Party shall notify the other Party in writing of any deviations from applicable Laws relevant to this Agreement of which any of its employees becomes aware. Each Party hereby certifies that it has not and will not employ or otherwise use in any capacity the services of any person or entity debarred under Section 21 USC 335a in performing any activities hereunder. Each Party shall notify the other Party in writing immediately if any such debarment relevant to this Agreement occurs or comes to its attention, and shall promptly remove any person or entity so disbarred from performing any activity or function related to the Research Program. Pfizer shall have the right, in its sole discretion, to terminate this Agreement immediately in the event of any such debarment, which termination shall be deemed a termination for cause.

Use of Human Materials. If any human cell lines, tissue, human clinical isolates or similar human-derived materials (“Human Materials”) have been or are to be collected or used in the Research Program by a Party or any Affiliate or Third Party acting on such Party’s behalf, such Party represents and warrants (i) that it has complied, or shall comply, with all applicable Laws relating to the collection or use of the Human Materials and (ii) that it has obtained, or shall obtain, all necessary approvals and appropriate informed consents, in writing, for the collection or use of such Human Materials. Each Party shall provide documentation of such approvals and consents to the other Party upon the other Party’s reasonable request. Each Party further represents and warrants that any such Human Materials that are used in the Research Program may be used as contemplated in this Agreement without any obligations to the individuals or entities (“Providers”) who contributed the Human Materials, including any obligations of compensation to such Providers or any other Third Party for the intellectual property associated with, or commercial use of, the Human Materials for any purpose.

Animal Research. Arvinas will comply with the Animal Welfare Act or any other applicable Laws relating to the care and use of laboratory animals. Pfizer encourages Arvinas to use the highest standards, such as those set forth in the Guide for the Care and Use of Laboratory Animals (NRC, 1996), for the humane handling, care and treatment of such research animals. Arvinas hereby certifies that prior to conducting any animal research at any Arvinas facility in connection with the Research Program, it shall obtain accreditation from AAALAC and shall maintain such accreditation for so long as it conducts such research. Any animals which are used by or on behalf of either Party in the course of the Research Program, or products derived from those animals, such as eggs or milk, will not be used for food purposes, nor will these animals be used for commercial breeding purposes.

License Grants.

License. Arvinas hereby grants to Pfizer, with respect to each Target, an exclusive license (even as to Arvinas) in the Territory under Arvinas Patent Rights, Arvinas Know-How, and Arvinas’ rights in the Joint Patent Rights and Joint Information and Inventions, with the right to grant and authorize sublicenses to the extent expressly provided below, to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize, have Commercialized and otherwise exploit Compounds and Products directed to such Target for any and all purposes, [**] (each, a “License”). [**].

Unblocking License. In addition to the licenses granted to Pfizer pursuant to Section 3.1.1, during the Term, on a Product-by-Product basis, in the event that [**], Arvinas hereby grants, and Arvinas hereby causes its Affiliates to grant, to Pfizer, subject to the terms and conditions of this Agreement and subject to any preexisting license grants to Third Parties, and to the extent Arvinas is legally able to do so, a fully-paid, non-exclusive, royalty-free, sublicensable license during the Term under such issued Patent Right for Pfizer to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize, have Commercialized and otherwise exploit Compounds and Products in accordance with this Agreement.

Notwithstanding the foregoing, on a Target-by-Target basis, Pfizer shall not, and shall have no right to, alone or through any Third Party, exercise or sublicense the relevant License, other than in order to complete the activities pursuant to the Research Program, unless and until Pfizer has exercised its Option with respect to such Target in accordance with Section 3.2 below.

Arvinas shall retain such rights under the foregoing grants as are necessary to conduct discovery and preclinical research activities with respect to the Targets and Compounds directed at a Target solely in connection with the Research Program and as set forth in each Research Plan.

Once a Target is no longer included under this Agreement, whether pursuant to Section 2.3, 3.2, Article 8 or otherwise, Pfizer shall have no further rights as granted above with respect to relevant Compounds or Products. In addition, no rights are granted to Pfizer under the Arvinas Patent Rights or Arvinas Know-How with respect to the use of any compound in connection with the mediation of proteasomal degradation of any target other than those Targets with respect to which Pfizer retains an exclusive license under Section 3.1.1.

Notwithstanding Arvinas’ sole ownership of Arvinas Technology Improvements as set forth in Section 2.7 and the exclusive license granted to Arvinas in Section 7.2.2(e) with respect to Arvinas Technology Improvements, (i) Arvinas may utilize Arvinas Technology Improvements arising in the course of performance of the Research Program or with respect to which rights are obtained from Pfizer hereunder only for Arvinas’ internal programs or for programs conducted by or on behalf of Third Parties who license Arvinas’ protein degradation technology, but not with respect to any Target that is included under an exclusive license granted under this Agreement at the relevant time, and (ii) Arvinas hereby grants to Pfizer a non-exclusive, worldwide, fully-paid license to utilize Arvinas Technology Improvements invented solely by Pfizer or its Affiliates or a Third Party acting on behalf of Pfizer or its Affiliates for any purposes, and to sublicense such rights solely in connection with a license of rights to a related Pfizer product.

The Parties understand and agree that, notwithstanding any other provision hereof, for so long as Pfizer has rights to the relevant Compound(s) under Section 3.1.1, Arvinas shall not have the right to practice itself or through an Affiliate, or grant a license to any Third Party under, any Arvinas Patent Rights claiming Arvinas Information and Inventions that specifically or generically claim or Cover any such Compound or a method of use of such a Compound, except as expressly authorized by Pfizer in writing; provided that in the event that any such Arvinas Patent Rights Cover, but do not claim, such a Compound or a method of use of such a Compound, Arvinas shall not grant any license under its interest in such Arvinas Patent Rights to any Third Party without the prior written consent of Pfizer, such consent to not be unreasonably withheld or delayed, and such consent to not require disclosure by Arvinas of any Third Party confidential information.

Pfizer shall have the right to grant sublicenses under the licenses granted in this Section 3.1, subject to any express limitations provided above; provided that Pfizer shall remain liable for the performance of any such sublicensee.

Arvinas hereby grants to Pfizer a non-exclusive, worldwide, perpetual, irrevocable, fully paid-up license, with the right to grant sublicenses through one or more tiers of sublicensees, under any Arvinas Information and Inventions and any Patent Rights claiming Arvinas Information and Inventions, in each case to the extent that it relates to a derivative, modification of or improvement to a Pfizer Compound, or to a product other than a PROTAC containing such a Pfizer Compound or a derivative, modification of or improvement thereto, or the manufacture, use or formulation thereof, to make, have made, use, sell, offer for sale, and import such Pfizer Compounds or products other than PROTACs.

Option. For each Target, Arvinas hereby grants to Pfizer an Option to obtain the right to exercise a License with respect to such Target as follows:

Upon (i) completion of the [**] with respect to such Target, (ii) completion of any Additional Work agreed to in accordance with Section 5.2.1 during the Option Period following the [**] with respect to such Target, (iii) completion of an [**] with respect to such Target that was Initiated prior to Option Exercise for the relevant Target, or (iv) upon any earlier termination of the Research Program Term by Pfizer pursuant to Section 8.3.1, Arvinas shall suspend its activities under the Research Program and provide to Pfizer the Deliverables with respect to such Target and Additional Work or Stage, as applicable (or in the event of early termination of the Research Program Term by Pfizer

Arvinas hereby grants to Pfizer an exclusive option to obtain the right to exercise the License with respect to each Target (“Option”). Pfizer may exercise its Option for a particular Target, at its sole discretion, by notifying Arvinas’ Alliance Manager in writing (“Option Notice”) at any time prior to [**] following Pfizer’s receipt of the Deliverables with respect to the Additional Work or the relevant Stage for such Target described in Section 3.2.1 (or in the event of early termination of the Research Term by Pfizer pursuant to Section 8.3.1, such of the Deliverables as are then available), subject to any earlier termination of this Agreement with respect to such Target in accordance with Article 8 (“Option Period”). Any such exercise of the Option by Pfizer pursuant to this Section 3.2.2 shall be deemed an “Option Exercise” for the relevant Target, effective as of the date of the relevant Option Notice. In the event that Additional Work with respect to the Exploratory Phase Stage is agreed by the Parties during an Option Period in accordance with Section 5.2.1 and no Option Exercise is made during such Option Period, there shall be an additional Option Period for such Target following completion of such Additional Work and Pfizer’s receipt of all Deliverables with respect to such Additional Work, during which period Pfizer may exercise its Option as provided above. In the event that an Additional Stage with respect to a given Target is agreed by the Parties during an Option Period in accordance with Section 5.2.2 and no Option Exercise is made during such Option Period, there shall be an additional Option Period for such Target following completion of such Additional Stage and Pfizer’s receipt of all Deliverables with respect to such Additional Stage, during which period Pfizer may exercise its Option by issuance of an Option Notice as provided above.

Upon receipt of an Option Notice for a particular Target in accordance with Section 3.2.2 above, (a) the Research Program for such Target shall terminate except for any relevant Additional Work or Additional Stage to be conducted thereafter as mutually agreed in accordance with Section 5.2, (b) in the event of Option Exercise following early termination of the Research Program Term by Pfizer pursuant to Section 8.3.1, any milestone payments under Sections 5.4.1 through 5.4.3 for portions of the Research Program that have not been Initiated under the Research Program with respect to such Target at such time shall no longer be due with respect to such Target, and (c) subject to its remaining payment obligations under Article 5, Pfizer may thereafter practice and exercise its rights under the License with respect to such Target as set forth under Section 3.1 above for the remainder of the Term of this Agreement as applicable to such Target.

In the event an Option Notice is not provided to Arvinas within the Option Period for a particular Target, and the Parties have not agreed to perform Additional Work for the relevant Target following the Exploratory Phase Stage in accordance with Section 5.2.1, and the Parties have not agreed to perform Additional Work for the relevant Target and Stage in accordance with Section 5.2.2, as applicable, the Research Program for such Target shall terminate upon expiration of such Option Period, and this Agreement shall be deemed terminated with respect to such Target in accordance with Section 8.2 (but without any [**] delay). Upon such termination, such Target shall no longer be designated as a “Target” hereunder, and all rights and obligations of the Parties under this Agreement with respect to such Target shall terminate except as expressly provided under Section 8.4.

Non-Exclusive Research Licenses. During the Research Program Term, Pfizer hereby grants to Arvinas a non-exclusive license in the Territory under the Pfizer Know-How, Pfizer Patent Rights and Pfizer Technology solely to the extent required for conducting the Research Program in accordance with the Research Plans. During the Research Program Term, Arvinas hereby grants to Pfizer a non-exclusive license in the Territory under the Arvinas Know-How and Arvinas Patent Rights and Arvinas Technology solely to the extent required for conducting the Research Program in accordance with the Research Plans. Such rights shall be personal and non-sublicensable except to permitted subcontractors as expressly set forth in Section 2.2.

Direct License to Affiliates. Pfizer may at any time request that Arvinas grant a license equivalent to the relevant License directly to an Affiliate of Pfizer by giving written notice designating to which Affiliate a direct license is to be granted. Upon receipt of any such notice, the Parties shall enter into and sign a separate direct license agreement with such designated Affiliate of Pfizer. All such direct license agreements shall be consistent with the terms and conditions of this Agreement, except for such modifications as may be required by the laws and regulations in the country in which the direct license will be exercised. The Parties further agree, as a condition to the grant of any such direct license, to make any amendments to this Agreement that are necessary to conform the combined terms of any such mutually agreed direct license agreements and this Agreement to the terms of this Agreement, as in effect at the relevant time, and to ensure that Arvinas does not incur any diminution of rights, losses, or expenses as a result of the issuance of any such direct licenses for which it is not made whole by Pfizer. In countries where the validity of such direct license agreements requires prior governmental approval or registration, such direct license agreements shall in no event become binding between the parties thereto until such approval or registration is granted, which approval or registration shall be obtained by Pfizer at Pfizer’s sole expense.

Target Substitution. Subject to Section 2.3.6, at any time prior to the [**] with respect to a given Initial Target or its applicable Substitute Target, Pfizer may, through written notice to Arvinas, replace such Target as further provided below. In Pfizer’s written notice, Pfizer will provide the Initial Target to be replaced and will propose a potential Substitute Target (the “Target Substitution Notice”). Arvinas will notify Pfizer in writing within [**] after the delivery of the Target Substitution Notice if the proposed Substitute Target is an Excluded Target. Otherwise, such proposed Substitute Target shall be deemed accepted by Arvinas. Provided that the proposed Substitute Target is accepted as provided above, such Substitute Target shall become a Target for all purposes under this Agreement and the replaced Initial Target or prior Substitute Target, as applicable, shall cease to be a Target for all purposes under this Agreement. [**] The Parties shall agree on the Research Plan for each Substitute Target that becomes a Target promptly following issuance of the relevant Target Substitution Notice, which Research Plan shall be substantially similar to the completed Research Plans attached to this Agreement as of the Effective Date, unless otherwise agreed in writing by the Parties.

No Implied Licenses. Except as specifically set forth in this Agreement, neither Party shall acquire any license or other intellectual property interest or other rights, by implication or otherwise, in any Information disclosed to it under this Agreement or under any patents or patent applications owned or controlled by the other Party or its Affiliates.

Development and Commercialization. Pfizer shall use Commercially Reasonable Efforts, at its own expense, to Develop and Commercialize at least one (1) Product directed to each Target in one Major Market Country. For each Target, within [**] following the end of each Calendar Year during the term of this Agreement and after the completion of the Research Program Term, and continuing until such time as payment of all potential milestone payments pursuant to Section 5.4 has been made with respect to such Target, Pfizer shall provide to Arvinas a written report which shall summarize Pfizer’s efforts to Develop and Commercialize Compounds and Products directed to such Target during the foregoing Calendar Year. Pfizer agrees that Arvinas may provide a copy of such written reports to Yale University (with all reasonable redactions requested by Pfizer), subject to the protections afforded to Arvinas’ “CONFIDENTIAL INFORMATION” under the Yale Agreement.

Exceptions to Diligence Obligations. Notwithstanding any provision of this Agreement to the contrary, Pfizer will be relieved of all Pfizer diligence obligations to the extent that:

Deemed Satisfaction of Pfizer Diligence Obligations. Without in any way expanding Pfizer’s obligations under this Agreement, Pfizer’s achievement of any milestone entitling Arvinas to receive a specific payment described in Section 5.4 will be deemed conclusive evidence that Pfizer has satisfied all Pfizer diligence obligations under this Agreement with respect to the relevant Target up to the date that such milestone is achieved. For the avoidance of doubt, the provisions of this Section 3.9 are intended only as examples of diligence constituting satisfaction of the Pfizer diligence obligations.

Assertion of Pfizer Diligence Obligation Claims. If Arvinas is or becomes aware of facts that might form a reasonable basis to allege that Pfizer has failed to meet any of its obligations under Section 3.7, or disputes an exception claimed by Pfizer with respect to those obligations pursuant to Section 3.8, then Arvinas will promptly notify Pfizer in writing of such potential alleged performance failure or dispute (each such potential alleged performance failure or dispute, a “Diligence Issue”). Promptly upon Pfizer’s receipt of any notice of a Diligence Issue pursuant to this Section 3.10, the Parties shall first submit such Diligence Issue to the Committee for resolution, and if no resolution is reached within [**], then the Parties shall try to resolve the Diligence Issue pursuant to the dispute resolution provisions set forth in Section 10.7.

Alliance Managers.

Appointment. Each Party shall, by written notice to the other Party, appoint an employee who shall oversee interactions between the Parties for all matters related to this Agreement (each an “Alliance Manager”). Such persons shall endeavor to ensure clear and responsive communication between the Parties and the effective exchange of information, and may serve as a single point of contact for any matters arising under this Agreement. The Alliance Managers shall have the right to attend all Committee meetings as non-voting participants and may bring to the attention of the Committee any matters or issues either of them reasonably believes should be discussed, and shall have such other responsibilities as the Parties may mutually agree in writing. Either Party may designate a replacement Alliance Manager by notice in writing to the other Party.

Responsibilities of the Alliance Managers. The Alliance Managers shall have the responsibility of creating and maintaining a constructive work environment between the Parties during the Research Program Term, and a constructive communication pathway thereafter. Without limiting the generality of the foregoing, each Alliance Manager shall:

identify and bring disputes and issues that may result in disputes (including any asserted occurrence of a material breach by a Party) to the attention of the Committee (for so long as it exists) or of the other Party’s Alliance Manager thereafter in a timely manner, and function as the point of first referral in all matters of conflict resolution;

provide a single point of communication for seeking consensus both internally within the Parties’ respective organizations and between the Parties;

plan and coordinate cooperative efforts, internal communications and external communications between the Parties with respect to this Agreement; and

take responsibility for ensuring that meetings and the production of meeting agendas and minutes occur as set forth in this Agreement, and that relevant action items resulting from such meetings are appropriately carried out or otherwise addressed.

Other Pfizer Programs. Arvinas acknowledges and agrees that nothing in this Agreement will be construed as a representation, warranty, covenant or inference that Pfizer will not itself Develop, Manufacture or Commercialize or enter into business relationships with one or more of its Affiliates or Third Parties to Develop, Manufacture or Commercialize products, programs, technologies or processes that are similar to or that may compete with any product, program, technology or process covered by this Agreement, provided that, for clarity, Pfizer will not use Arvinas’ Information or the Arvinas Know-How in breach of this Agreement. The Parties agree and acknowledge that nothing in this Agreement shall be deemed to prohibit the unintentional internal use by Pfizer personnel of Residual Information in connection with performance of research projects on behalf of Pfizer, where “Residual Information” means ideas, concepts, know-how, and techniques in non-tangible form retained in the unaided memory of persons who have had access to Information of Arvinas. A person’s memory is only unaided if the person has not intentionally memorized the Information for the purpose of retaining and subsequently using or disclosing the relevant Information, and did not involve reference to tangible materials intended to assist recall of such Information. The Parties agree and acknowledge that Pfizer will have a right to use for any and all purposes any Excluded Information that is provided by Arvinas to Pfizer under this Agreement without the prior written consent of Pfizer, Pfizer’s Alliance Manager or Pfizer’s Committee representative.

Nondisclosure and Nonuse Obligation. Each Party agrees that, for so long as this Agreement is in effect and for a period of [**] thereafter, a Party (the “Receiving Party”) receiving Information of the other Party hereunder (the “Disclosing Party”) (or that has received any such Information from the other Party prior to the Effective Date) shall (i) maintain in confidence

Exceptions. The obligations under Section 4.1 shall not apply with respect to any portion of the Information that the Receiving Party can show by competent proof:

is known by the Receiving Party at the time of its receipt, and not through a prior disclosure by the Disclosing Party, as documented by the Receiving Party’s business records;

is in the public domain by use or publication before its receipt from the Disclosing Party, or thereafter enters the public domain through no fault of the Receiving Party;

is subsequently disclosed to the Receiving Party on a non-confidential basis by a Third Party who may lawfully do so; or

is developed by the Receiving Party independently of Information received from the Disclosing Party, as documented by the receiving Party’s business records.

Authorized Disclosure. To the extent (and only to the extent) that it is reasonably necessary or appropriate to fulfill its obligations or exercise its rights under this Agreement, the Receiving Party may disclose Information belonging to the Disclosing Party in the following instances:

if disclosed to governmental or other regulatory agencies in order to obtain patents or to gain or maintain approval to conduct Clinical Trials or to market Product, but such disclosure may be only to the extent reasonably necessary to obtain patents or authorizations in a manner consistent with rights granted under this Agreement;

if deemed necessary by Arvinas to be disclosed to (i) its Affiliates, agent(s), consultant(s), or other Third Parties for the conduct of the Research Program in accordance with the terms of this Agreement, (ii) to Yale University in connection with Arvinas’ obligations and rights under the Yale Agreement, or (iii) as reasonably appropriate in connection with the exercise of the rights granted hereunder with respect to Arvinas Technology Improvements or Joint Information and Inventions, or if deemed necessary by Pfizer to be disclosed to its Related Parties, Affiliates, agent(s), consultant(s), or other Third Parties for the Development, Manufacturing Commercialization or use of Compound or Product (or for such entities to determine their interest in performing such activities) in accordance with the terms of this Agreement, in all cases on the condition that such Third Parties agree to be bound by confidentiality and non-use obligations that substantially are no less stringent than those confidentiality and

if deemed necessary by counsel to the Receiving Party to be disclosed to such Party’s attorneys, independent accountants or financial advisors for the sole purpose of enabling such attorneys, independent accountants or financial advisors to provide advice to the Receiving Party, on the condition that such attorneys, independent accountants and financial advisors agree to be bound by, or are bound by ethical rules to comply with, the confidentiality and non-use obligations contained in this Agreement; provided, however, that the term of confidentiality for such attorneys, independent accountants and financial advisors shall be no less than [**];

prosecuting or defending litigation; or

subject to Sections 4.4 and 4.5, complying with applicable Laws (including the rules and regulations of the Securities and Exchange Commission or any national securities exchange) and with judicial process, if in the reasonable opinion of the Receiving Party’s counsel, such disclosure is necessary for such compliance.

Required Disclosure. Where reasonably possible and subject to Section 4.5, if a Party is required by judicial or administrative process to disclose Information that is subject to the non-disclosure provisions of this Article 4, such Party shall promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure obligations. The Party disclosing Information of the other Party pursuant to applicable Laws or court order shall take reasonable steps, including obtaining an order of confidentiality if possible, to ensure the continued confidential treatment of such Information. The Receiving Party shall furnish only that portion of the Information which it is advised by counsel is legally required whether or not a protective order or other similar order is obtained. Information that is disclosed in accordance with this Section 4.4 shall remain otherwise subject to the confidentiality and non-use provisions of this Article 4 except to the extent that such permitted disclosure results in a public disclosure of such information (otherwise than by breach of this Agreement).

Securities Filings. In the event either Party proposes to file with the Securities and Exchange Commission, or the securities regulators of any state or other jurisdiction, a registration statement or any other disclosure document which describes or refers to this Agreement under the Securities Act of 1933, as amended, the Securities Exchange Act, of 1934, as amended, or any other applicable securities Laws, the Party shall notify the other Party of such intention and shall provide such other Party with a copy of relevant portions of the proposed filing not less

Terms of Agreement. The existence and the terms and conditions of the Agreement that the Parties have not specifically agreed to disclose pursuant to Section 4.5 or 4.8 shall be considered Information of both Parties. Either Party may disclose such terms to a bona fide investor, investment banker, acquiror, merger partner or other potential financial partner, and their attorneys and agents, provided that each such Person to whom such information is to be disclosed is informed of the confidential nature of such information and has entered into a written agreement with the Party requiring such Person to keep such information confidential.

Publication.

By Arvinas. Arvinas shall have no right to publish any results of the Research Program without the prior written consent of Pfizer, provided that no such consent shall be required with respect to any publication of Arvinas Technology Improvements that does not include any Information of Pfizer. Pfizer acknowledges Arvinas’ desire to use genericized results included within the Arvinas Information and Inventions to promote interest in and use of the Arvinas Technology and will discuss in good faith the possible permitted disclosure of such information.

By Pfizer. Pfizer shall have the right to make publications relating to the Research Program, Compounds and Products solely to the extent relating to a Compound or Product for which Pfizer has exercised its Option hereunder, provided that Pfizer does not publish Arvinas Know-How relating to the Arvinas Technology or the Arvinas Technology Improvements without Arvinas’ prior consent, which shall not be unreasonably withheld or delayed. Once any such abstract or manuscript is accepted for publication, Pfizer shall use reasonable efforts to provide Arvinas with a copy of the final version of the manuscript or abstract.

General. For clarification, this Section 4.7 shall not apply with respect to the use and disclosure of Information as specifically provided for in other Sections of this Article 4 (i.e., a disclosure expressly permitted and made in accordance with another Section of this Article 4 shall not be subject to this Section 4.7). In addition, the Parties agree that it shall not be unreasonable for either Party to withhold its consent to any disclosure as provided above in order to ensure that there is sufficient opportunity to file patent applications on relevant Inventions in accordance with the provisions of Section 7.2 or 7.3 prior to any such disclosure.

Publicity/Use of Names. Neither Party shall use the name, trademark, trade name or logo of the other Party, its Affiliates or their respective employee(s) in any publicity, promotion, news release or disclosure relating to this Agreement or its subject matter, without the prior express written permission of the other Party, except for those disclosures expressly authorized under

Injunctive Relief. The Parties hereto understand and agree that remedies at law may be inadequate to protect against any breach of any of the provisions of this Article 4 by either Party or their employees, agents, officers or directors or any other Person acting in concert with it or on its behalf. Accordingly and notwithstanding Section 10.7, each Party shall be entitled to seek injunctive relief by a court of competent jurisdiction against any action that constitutes any such breach of this Article 4.

Upfront Fee. In consideration for the Target Exclusivity granted by Arvinas pursuant to Section 2.10, Arvinas’ obligations hereunder, and the licenses granted herein under the Arvinas Patent Rights and Arvinas Know-How and Arvinas’ rights in the Joint Patent Rights, upon the terms and conditions contained herein, Pfizer shall pay Arvinas Twenty-Five Million Dollars (US$25,000,000), due and payable within [**] following Pfizer’s receipt of the invoice therefor but in no event prior to [**].

Additional Research Program Activities.

In the event that, following delivery of the relevant Deliverables as set forth in the Research Plan for a given Target and Stage, up to and including the Exploratory Phase Stage, Pfizer desires to have Arvinas pursue additional work before progressing to the next Stage or before exercising its Option, the Parties shall discuss in good faith such additional work and negotiate a revised Research Plan, including relevant Deliverables, and budget therefor (“Budget”). If the Parties agree on such amended Research Plan and Budget in writing and within the relevant Election Period (or Option Period with respect to Additional Work following the Exploratory Phase Stage), such agreement to not be unreasonably withheld by Arvinas if such Additional Work would occur prior to the Initiation of the Exploratory Phase Stage of the applicable Research Plan, Arvinas shall be obligated to perform such additional work (“Additional Work”), and Pfizer shall pay for such activities in accordance with the relevant Budget and mutually agreed payment terms.

In the event that, following completion of the [**], and any related Additional Work agreed pursuant to Section 5.2.1 for a given Target, Pfizer desires to have Arvinas pursue additional work as part of the Research Program with respect to such Target and involving work related to lead optimization (“Lead Optimization Efforts”), whether such activities are to occur before or after exercising the relevant Option, the Parties shall upon request of Pfizer discuss in good faith such additional work and negotiate a revised Research Plan, including relevant Deliverables and Budget.

Audits.

Pfizer shall keep, and shall require its Related Parties to keep, complete and accurate records in sufficient detail to enable the amounts payable hereunder to be determined. Upon [**] written request of Arvinas and not more than [**], Pfizer and its Related Parties shall permit an independent certified public accounting firm of nationally recognized standing selected by Arvinas and reasonably acceptable to Pfizer, at Arvinas’ expense, to have access during normal business hours to such of the records of Pfizer and

If such accounting firm correctly identifies a discrepancy made during such period, Pfizer shall pay to Arvinas the amount of any underpayment discrepancy within [**] of the date Arvinas delivers to Pfizer such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties. The fees charged by such accounting firm shall be paid by Arvinas; provided, however, that if such audit uncovers an underpayment of royalties by Pfizer that exceeds [**] percent ([**]%) of the total royalties owed for the relevant period, then the fees of such accounting firm shall be paid by Pfizer. If such accounting firm concludes that Pfizer overpaid royalties to Arvinas, then Arvinas will refund such overpayments to Pfizer, within [**] of the date Arvinas receives such accountant’s report or, if such overpayment is more than [**] dollars, then Arvinas and Pfizer shall mutually agree on mechanism for such refund, which mechanism may include a credit against any future payment by Pfizer to Arvinas or a repayment schedule.

Pfizer shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the sublicensee to make reports to Pfizer, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by Arvinas’ independent accountant to the same extent required of Pfizer under this Agreement.

Upon the expiration of [**] following the end of any Pfizer Year, the calculation of royalties payable with respect to such Pfizer Year shall be binding and conclusive upon Arvinas, and Pfizer and its Related Parties shall be released from any liability or accountability with respect to royalties for such Pfizer Year.

Arvinas shall treat all financial information subject to review under this Section 5.9 or under any relevant sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with Pfizer or its Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

In the case of sales outside the United States, the rate of exchange to be used in computing the monthly amount of currency equivalent in United States dollars due Arvinas shall be made at the monthly rate of exchange utilized by Pfizer in its worldwide accounting system.

Taxes. Arvinas shall be liable for any and all taxes, duties and other levies applied by a government of any country of the Territory on those payments that are made by Pfizer to Arvinas under this Agreement.

Withholding Taxes. In the event that any payments due to Arvinas are subject to withholding tax required by applicable Law to be paid to the taxing authority of any foreign country, Pfizer may deduct the amount of such tax from the applicable payment otherwise payable to Arvinas. In such event, Pfizer shall, on a timely basis, notify Arvinas of such obligation, pay the taxes to the proper taxing authority and send evidence of the obligation together with proof of payment thereof to Arvinas following that payment.

Value Added Tax (“VAT”). It is understood and agreed between the Parties that any payments made under this Agreement are exclusive of any value added or similar tax (“VAT”), which shall be added thereon as applicable. Where VAT is properly added to a payment made under this Agreement, the party making the payment will pay the amount of VAT only on receipt of a valid tax invoice issued in accordance with the laws and regulations of the country in which the VAT is chargeable.

Tax Cooperation. To the extent that the Party making a payment is required to deduct and withhold taxes on any payments under this Agreement, the Party making such payment shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to the payee an official tax certificate or other evidence of such withholding sufficient to enable the payee to claim such payments of taxes. The payee shall provide any tax forms to the Party making such payment that may be reasonably necessary in order for such Party not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. The payee shall use reasonable efforts to provide any such tax forms to the Party making the payment at least [**] prior to the due date for any payments for which the payee desires that the Party making the payment apply a reduced withholding rate. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by Law, of withholding taxes, VAT, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or VAT.

Blocked Currency. If by applicable Law or fiscal policy of a particular country, conversion into United States dollars or transfer of funds of a convertible currency to the United States is restricted or forbidden, royalties accrued in that country shall be paid to Arvinas in the country in local currency by deposit in a local bank designated by Arvinas, unless the Parties otherwise agree.

Option of Pfizer to Prosecute and Maintain Arvinas Program Patent Rights. Arvinas shall give notice to Pfizer of any desire to cease prosecution or maintenance of any of the Arvinas Program Patent Rights in any country in the Territory and, in such case, shall permit Pfizer, in its sole discretion, to continue prosecution or maintenance of such Arvinas Program Patent Rights in any or all countries in the Territory in which Arvinas has elected not to prosecute or maintain such patent applications at Pfizer’s own expense and in the name of Arvinas, subject to Section 7.2.2(c).

Procedures. Notwithstanding any other provision hereof, each Party shall use all reasonable efforts to, in activities conducted in accordance with this Section 7.2, file Patent Rights claiming Inventions in such a manner as to ensure that Compounds and uses of Compounds are not claimed in the same patent applications as those claiming either Inventions within Arvinas Technology Improvements or Inventions that are applicable to PROTACs in general. In the event that either Party reasonably believes that it cannot file such claims in separate filings, such Party shall consult with the other Party regarding such matter and cooperate in good faith with such other Party to effect a solution regarding ownership of and rights to any relevant Patent Rights claiming such mixed Inventions consistent with the intent of the other relevant provisions of this Agreement. In situations where, subject to compliance with the foregoing requirements, a patent application of mixed Inventions claims Arvinas Technology Improvements and other Inventions, and Pfizer is the sole owner or joint owner of such other Inventions claimed in such application (a “Mixed Application”), the Parties shall jointly own any such Mixed Application.

Filing, prosecution, enforcement and defense of any such Mixed Applications shall be performed in accordance with Sections 7.2.2(b) and 7.5 as for Joint Information and Inventions and Joint Patent Rights.

Reallocation of Responsibilities. Upon request of Pfizer, the Parties shall negotiate in good faith an amendment to this Agreement and this Article 7 allowing Pfizer to have first right to control, at Pfizer’s expense, the filing, prosecution, maintenance, enforcement and defense of Arvinas Program Patent Rights to the extent specifically or generically claiming Compounds or Products exclusively licensed to Pfizer hereunder.

Pfizer Patent Rights. Pfizer shall have the exclusive right, at its sole expense, to file, prosecute and maintain any and all Pfizer Patent Rights. Pfizer shall also have the sole and exclusive right to enforce and defend the Pfizer Patent Rights, including without limitation any interference, opposition, reissue or reexamination proceeding relating to Pfizer Patent Rights and any infringement of Pfizer Patent Rights.

Interference, Opposition, Reexamination and Reissue.

Arvinas shall, within [**] of any of its executive officers learning of such event, inform Pfizer of any request for, or filing or declaration of, any interference, opposition, reissue or reexamination relating to Arvinas Patent Rights which cover the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder or Joint Patent Rights. Pfizer shall, within [**] of any of its executive officers learning of such event, inform Arvinas of any request for, or filing or declaration of, any interference, opposition, reissue or reexamination relating to Arvinas Patent Rights which cover the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder or Joint Patent Rights. Pfizer and Arvinas shall thereafter consult and cooperate fully to determine a course of action with respect to any such proceeding. Pfizer shall have the right to review and approve any submission to be made in connection with such proceeding.

Arvinas shall not initiate any reexamination, interference or reissue proceeding relating to Arvinas Patent Rights covering the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder or Joint Patent Rights without the prior written consent of Pfizer, which consent shall not be unreasonably withheld or delayed. Pfizer shall not initiate any reexamination, interference or reissue proceeding relating to Arvinas Patent Rights covering the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder or Joint Patent Rights without the prior written consent of Arvinas, which consent shall not be unreasonably withheld or delayed.

In connection with any interference, opposition, reissue, or reexamination proceeding relating to Arvinas Patent Rights or Joint Patent Rights, Pfizer and Arvinas will cooperate fully and will provide each other with any information or assistance that either may reasonably request. For Arvinas Patent Rights covering the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder or Joint Patent Rights, the responsible Party shall keep the other Party informed of developments in any such action or proceeding, including, to the extent permissible by applicable Laws, consultation and approval of any settlement, the status of any settlement negotiations and the terms of any offer related thereto.

Arvinas shall bear the expense of any interference, opposition, reexamination, or reissue proceeding relating to Arvinas Patent Rights that Arvinas elected to prosecute and maintain. Pfizer shall control and bear the expense of any interference, opposition, reexamination, or reissue proceeding relating to Pfizer Patent Rights or Joint Patent Rights that Pfizer elected to prosecute and maintain.

Regardless of which Party has the right to initiate and prosecute such action, both Parties shall, as soon as practicable after receiving notice of such action, convene and consult with each other regarding the appropriate course of conduct for such action. The non-initiating Party shall have the right to be kept fully informed and participate in decisions regarding the appropriate course of conduct for such action, and the right to join and participate in such action.

Enforcement and Defense.

Each Party shall give the other Party notice of either (i) any infringement of Arvinas Patent Rights or Joint Patent Rights, or (ii) any misappropriation or misuse of Arvinas Know-How, in each case that is reasonably relevant to the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder and that comes to such Party’s attention. Pfizer and Arvinas shall thereafter consult and cooperate fully to determine a course of action, including the commencement of legal action by either or both Pfizer and Arvinas, to terminate any such infringement of Arvinas Patent Rights or Joint Patent Rights or any misappropriation or misuse of Arvinas Know-How, subject to the provisions set forth below.

Except as provided under Section 7.6 or any mutually agreed amendment made in accordance with Section 7.2.2(f), Arvinas, upon notice to Pfizer, shall have the first right to initiate and prosecute any such legal action at its own expense, or to control the defense of any declaratory judgment action, relating to Arvinas Patent Rights or Arvinas Know-How. Pfizer shall have the right to join any such action initiated by Arvinas to the extent permissible by law. With respect to any such legal action regarding an infringement of any Arvinas Patent Right that directly impacts any exclusive rights of Pfizer hereunder regarding any Compound or Product, if Arvinas does not initiate any such legal action, at least [**] prior to the deadline for bringing an action without resulting loss of rights, of any written request by Pfizer for Arvinas to do so following consultation in accordance with Section 7.5.1, Pfizer shall have the right, but shall not be obligated, to bring an infringement action with respect to such infringement solely to the extent directly related to Pfizer’s exclusive rights hereunder (i.e., not related to any PROTACs directed to any target other than a Target) at its own expense, and under its own direction and control, or settle any such action, proceeding or dispute by license, subject to the following. Arvinas shall have the right to participate and be represented in any such suit by its own counsel at its own expense, provided that Pfizer shall retain overall responsibility for the prosecution of such suit or proceedings in such event. No settlement of any such action or proceeding which restricts the scope, or adversely affects the enforceability, of an Arvinas Patent Right, or which could be reasonably expected to have a material adverse financial impact on Arvinas, may be entered into by Pfizer without the prior written consent of Arvinas, which consent shall not be unreasonably withheld, delayed or conditioned.

Pfizer, upon notice to Arvinas, shall have the first right to initiate and prosecute any legal action at its own expense and in the name of Arvinas and Pfizer, or to control the defense of any declaratory judgment action, relating to Joint Patent Rights. Pfizer shall promptly inform Arvinas if it elects not to exercise such first right and Arvinas shall thereafter have the right to either initiate and prosecute such action or to control the defense of such declaratory judgment action. Each Party shall have the right to be represented by counsel of its own choice. No settlement of any such action or proceeding which restricts the scope, or adversely affects the enforceability, of any Joint Patent Right, or which could reasonably be expected to have a material adverse financial impact on the other Party, may be entered into by either Party without the prior written consent of the other Party, which consent shall not be unreasonably withheld, delayed or conditioned.

For any action to terminate any infringement of Arvinas Patent Rights or Joint Patent Rights, or any misappropriation or misuse of Arvinas Know-How, in the event that a Party is unable to initiate or prosecute any such action permitted hereunder solely in its own name, the other Party will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for such Party to initiate litigation to prosecute and maintain such action. If Yale University is required to join as a party in such action, Arvinas shall use all reasonable efforts to cause Yale University to join and provide reasonable assistance. In connection with any action brought hereunder, Pfizer and Arvinas will cooperate fully and will provide each other with any information or assistance that either may reasonably request. The requesting Party shall reimburse the other Party for the documented external costs the other Party reasonably incurs in providing any such assistance as specifically requested in writing. Each Party shall keep the other informed of developments in any action or proceeding, hereunder including, to the extent permissible by applicable Laws, consultation on and approval of any settlement, the status of any settlement negotiations and the terms of any offer related thereto.

If either Party brings an action or proceeding under this Section 7.5 and subsequently ceases to pursue or withdraws from such action or proceeding, it shall promptly notify the other Party and the other Party may substitute itself for the withdrawing Party under the terms of this Section 7.5.

In the event that either Party exercises the rights conferred in this Section 7.5 and recovers any damages or other sums in such action, suit or proceeding or in settlement thereof, such damages or other sums recovered shall first be applied to all out-of-pocket costs and expenses incurred by the Parties in connection therewith, including attorneys’ fees. Except as otherwise provided in this Section 7.5, each Party will bear its own expenses with respect to any suit or other proceeding against an infringer. If such recovery is insufficient to cover all out-of-pocket costs and expenses of both Parties, it shall be shared in proportion to the total of such costs and expenses incurred by each Party. If after such reimbursement any funds shall remain from such damages or other sums recovered, such funds shall be divided as follows: (i) as to ordinary damages based on lost sales or profit, a) if Pfizer is the Party bringing suit or bears [**] of the out-of-pocket costs and expenses of Arvinas in such action, or if Arvinas is the Party bringing suit but Pfizer has agreed as of the initiation of such action to bear [**] percent ([**]%) of the out-of-pocket costs and expenses incurred by Arvinas in connection therewith, Pfizer shall retain such funds and Arvinas shall receive payment equivalent to royalty payments that would have been due to Arvinas under this Agreement had the infringing sales that Pfizer lost to the infringer been made by Pfizer, c) and if Arvinas is the Party bringing suit and Pfizer has not agreed as of the initiation of such action to bear [**] percent ([**]%) of the out-of-pocket costs and expenses incurred by Arvinas in connection therewith, Arvinas shall retain [**] percent ([**]%) of such funds and provide [**] percent ([**]%) thereof to Pfizer, and (ii) as to special or punitive damages, the Parties shall collect in proportion to the ordinary damages received, provided that Arvinas shall in any event receive at least [**] percent ([**]%) thereof.

Patent Certification and Enforcement and Defense against Generic Applicant. Arvinas shall inform Pfizer of any certification reasonably relevant to the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder regarding any Arvinas Patent Rights or Joint Patent Rights that it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or its successor provisions or any similar provisions in a country in the Territory other than the United States, and shall provide Pfizer with a copy of such certification within [**] of receipt. Pfizer shall inform Arvinas of any certification reasonably relevant to the Development or Commercialization of any Compound or Product exclusively licensed by Pfizer hereunder regarding any Arvinas Patent Rights or Joint Patent Rights that it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or its successor provisions or any similar provisions in a country in the Territory other than the United States, and shall provide Arvinas with a copy of such certification within [**] of receipt. For countries in which there is no patent certification procedure or similar provision, each Party shall promptly give the other party notice of any Generic registration, marketing approval or launch activity relating to any Product exclusively licensed by Pfizer hereunder regarding any Arvinas Patent Rights or Joint Patent Rights. Arvinas’ and Pfizer’s rights with respect to the initiation and prosecution of any legal action as a result of such certification or activity or any recovery obtained as a result of such legal action shall be as defined in Section 7.5; provided, however, that with respect to Arvinas Patent Rights, Pfizer shall have the first right to initiate and prosecute any such action, at its own expense, and shall inform Arvinas of such decision within [**] of the notification or Pfizer’s receipt of the certification, after which time Arvinas shall have the right to initiate and prosecute such action, at its own expense. With respect to Joint Patent Rights, Pfizer shall have the first right to initiate, prosecute and control any action, at its own expense, and shall inform Arvinas of such decision within [**] of the notification or Pfizer’s receipt of the certification, after which time Arvinas shall have the right to initiate and prosecute such action, at its own expense. Regardless of which Party has the right to initiate and prosecute such action, both Parties shall, as soon as practicable after receiving notice of such certification or activity, convene and consult with each other regarding the appropriate course of conduct for such action. The non-initiating Party shall have the right to be kept fully informed and participate in decisions regarding the appropriate course of conduct for such action, and the right to join and participate in such action.

Patent Term Restoration and Extension. The Parties agree to cooperate and to take reasonable actions to maximize the protections available under the provisions of 35 U.S.C. 102(c) under the ▇▇▇▇▇-▇▇▇▇▇ America Invents Act for US patents and patent applications, as well as any and all patent extension provisions outside of the USA. The Parties shall cooperate with each other, including by providing necessary information and assistance as the other Party may reasonably request, in obtaining patent term extensions or supplemental protection certificates or their equivalents in any country in the Territory where applicable to Arvinas Patent Rights or Joint Patent Rights. In the event that elections with respect to obtaining such patent term extensions are to be made with respect to any Patent Right claiming an Invention that specifically claims Compounds or Products subject to an exclusive license granted to Pfizer hereunder, Pfizer shall have the right to make the election and Arvinas agrees to abide by such election.

Infringement Claims. Each of Arvinas and Pfizer shall promptly inform the other in writing of any written notice to it of alleged infringement or misappropriation, based on the making, using, keeping, importing, exporting or selling of a Product, of a Third Party’s intellectual property rights of which it shall become aware. Neither Party shall acknowledge to a Third Party the validity of any such allegation or admit liability without the prior written consent of the other Party, such consent to not be unreasonably withheld or delayed. Pfizer and Arvinas shall each keep the other advised of all material developments in the conduct of any proceedings in defending any claim of such alleged infringement or misappropriation and shall cooperate with the other in the conduct of such defense. In no event may either Party settle any such infringement or misappropriation claim in a manner that would limit the rights of the other Party or impose any obligation on the other Party, without such other Party’s prior written consent, such consent not to be unreasonably withheld or delayed.

Patent Marking. Solely with respect to Yale Licensed Patents, to the extent commercially feasible and consistent with Pfizer business practices, Pfizer shall use commercially reasonable efforts to ▇▇▇▇, and shall cause its Related Parties to use commercially reasonable efforts to ▇▇▇▇, all Products that are manufactured or sold under this Agreement with the number of each issued Yale Licensed Patent Controlled by Arvinas that applies to such Products.

Licensed Patent Challenges (Yale Agreement). The Parties acknowledge and agree that, pursuant to the Yale Agreement, Arvinas has certain obligations and may incur penalties based on (i) any challenge or opposition to the validity, patentability, enforceability or non-infringement of any of the Yale Licensed Patents (as defined herein and under the Yale Agreement”), or any actions otherwise opposing any of such Yale Licensed Patents, if brought by a sublicensee (Pfizer, its Affiliates or sublicensees under this Agreement) anywhere in the world, or (ii) any assistance with respect to any of the foregoing actions which any of Pfizer, its Affiliates or sublicensees provides to a Third Party anywhere in the world (except as required under a court order or subpoena) (any such action or assistance under (i) or (ii), a “Licensed Patent Challenge”). Accordingly, Pfizer hereby agrees to indemnify and hold Arvinas harmless with respect to any damages incurred by Arvinas under Section 6.3 of the Yale Agreement as a result of any Licensed Patent Challenge by Pfizer, its Affiliates or its sublicensees. For avoidance of doubt, Pfizer does not agree to indemnify Arvinas for any Licensed Patent Challenge brought by Arvinas, its Affiliates or any of its other sublicensees with respect to the Yale Agreement. In addition, Pfizer hereby agrees that neither Pfizer nor any of its Affiliates or its sublicensees shall bring a Licensed Patent Challenge without first providing Arvinas and Yale University with at least thirty (30) days prior written notice setting forth (a) those claims and patents that will be challenged or claimed not to be infringed, (b) a statement of the factual and legal basis for the challenge, and (c) an identification of prior art and other matters believed to invalidate any claim of a Yale Licensed Patent or which supports the claim that a Yale Licensed Patent is not infringed.

Term and Expiration. This Agreement shall be effective as of the Effective Date and unless terminated earlier pursuant to Sections 8.2 or 8.3, this Agreement shall continue in full force and effect until one or more Products has received Marketing Authorization and, thereafter, until expiration of all royalty obligations hereunder.

Termination by Pfizer. Notwithstanding anything contained herein to the contrary, Pfizer shall have the right to terminate this Agreement, either in its entirety or in relation to any Target and relevant Compounds and Products under this Agreement, at any time for any or no reason in its sole discretion by giving sixty (60) days’ advance written notice to Arvinas.

Termination for Cause.

Cause for Termination. This Agreement may be terminated at any time during the term of this Agreement:

upon written notice by a Party if the other Party is in breach of its material obligations hereunder and has not cured such breach within [**] after notice requesting cure of the breach (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [**] following such notice); provided, however, in the event of a good faith dispute with respect to the existence of a material breach, the relevant cure period shall be tolled until such time as such dispute is resolved pursuant to Section 10.7; or

by either Party upon the filing or institution of bankruptcy, reorganization, liquidation or receivership proceedings, or upon an assignment of a substantial portion of the assets for the benefit of creditors by the other Party; provided, however, that in the case of any involuntary bankruptcy proceeding such right to terminate shall only become effective if the Party consents to the involuntary bankruptcy or such proceeding is not dismissed within [**] after the filing thereof.

Notwithstanding the foregoing, any termination of this Agreement by Pfizer pursuant to Section 8.3.1(a) shall apply to this Agreement in its entirety, or be limited in force and effect to the Target to which such material breach relates, as Pfizer may elect in its sole discretion in writing at the time of termination, and any termination of this Agreement by Arvinas pursuant to Section 8.3.1(a) for breach of Sections 3.7, 5.3 or 5.4 shall be limited in force and effect to the Target (and related Compounds and Products) to which such material breach relates.

Effect of Termination.

In the event of termination of this Agreement in its entirety by Pfizer under Section 8.2, the Research Program Term shall terminate and all rights and licenses granted by Arvinas to Pfizer under Article 3 shall be terminated and all relevant rights shall revert to Arvinas.

In the event of partial termination of this Agreement by Pfizer under Section 8.2 with respect to any Target, all rights and licenses granted by Arvinas to Pfizer under Article 3 with respect to the relevant Target and related Compounds and Products shall be terminated and all relevant rights shall revert to Arvinas, and any exclusivity pursuant to Section 2.10 with respect to the relevant Target shall terminate.

In the event of termination of this Agreement in its entirety by Arvinas pursuant to Section 8.3.1, the Research Program Term shall terminate, all rights and licenses granted by Arvinas to Pfizer pursuant to this Agreement shall terminate and any exclusivity pursuant to Section 2.10 shall terminate.

In the event of termination of this Agreement in its entirety by Pfizer pursuant to Section 8.3.1, the Research Program Term shall terminate, along with all rights and licenses granted by Arvinas to Pfizer pursuant to this Agreement, except as expressly provided in Section 3.2; provided, however, that, unless otherwise elected by Pfizer in a written notice to Arvinas, Pfizer shall, with respect to any Target for which the Option has been exercised and all relevant and undisputed payments that have accrued pursuant to Article 5 have been made as of the effective date of termination, retain its license under Section 3.1 with respect to the relevant Target, Compounds and Products in accordance with the terms of this Agreement, and associated payments accruing after the effective date of termination shall be owed and made in accordance with the terms of Article 5, provided that any payments that may become due and owing will be paid at [**] percent ([**]%) of the amounts set forth in Article 5.

Upon termination of this Agreement by Pfizer pursuant to Section 8.2, or by Arvinas pursuant to Section 8.3.1, Pfizer and its Affiliates, sublicensees and distributors shall be entitled, during the [**] period immediately following the effective date of termination, to finish any work-in-progress and to sell any Product or Compound remaining in inventory, subject to compliance with the terms of this Agreement including those regarding the payment of royalties.

For clarity, any rights that have become fully paid and perpetual in accordance with Section 5.5.1(c) shall survive any termination of this Agreement.

No later than [**] after the effective date of any such termination, each Party shall return or cause to be returned to the other Party all Information of the other Party relevant to the terminated rights that is in tangible form and all copies thereof; provided, however, that each Party may retain any such Information to the extent reasonably necessary for such Party’s continued practice under any license(s) or rights which do not terminate pursuant to this Article 8, and may keep one copy of Information received from the other Party in its confidential files for record purposes. In addition, Pfizer shall, within [**] after the effective date of such termination by Arvinas, return or cause to be returned to Arvinas all relevant substances or compositions delivered or provided by Arvinas hereunder, as well as any other relevant material provided by Arvinas in any medium, provided, however, that Pfizer may retain any such materials to the extent reasonably necessary for Pfizer’s continued practice under any license(s) or rights which do not terminate pursuant to this Article 8.

All licenses and rights to licenses granted under or pursuant to this Agreement by Arvinas to Pfizer are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code (i.e., Title 11 of the U.S. Code) (the “Code”) , licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code. If (a) a case under the Code is commenced by or against Arvinas, (b) this Agreement is rejected as provided in the Code and (c) Pfizer elects to retain its rights hereunder as provided in Section 365(n) of the Code, then Arvinas (in any capacity, including debtor-in-possession) and its successors and assigns (including any trustee) shall provide to Pfizer all intellectual property licensed by Pfizer hereunder, and agrees to grant and hereby grants to Pfizer and its Affiliates a right to access and to obtain possession of and to benefit from and, in the case of any chemical or biological material or other tangible item of which there is a fixed or limited quantity, to obtain a pro rata portion of, all “embodiments” of intellectual property licensed hereunder pursuant to Section 365(n) of the Bankruptcy Code, and all other embodiments of such intellectual property in the possession and control of any Third Party but which Arvinas has the right to access or benefit from and to make available to Pfizer. Arvinas shall not interfere with the exercise by Pfizer or its Affiliates of rights and licenses to intellectual property licensed hereunder and embodiments thereof in accordance with this Agreement. The foregoing provisions of Section 8.4(h) are without prejudice to any rights Pfizer may have arising under the Code or other applicable Laws.

Additional Effects of Expiration or Termination; Survival. Expiration or termination of this Agreement shall not relieve the Parties of any obligation (including any payment obligation) accruing prior to such expiration or termination. Any expiration or termination of this Agreement shall be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination, including the obligation to pay royalties for Product or Compound sold prior to such expiration or termination. In addition, the provisions of Article 1, Article 4, Article 6, Article 7, Article 8, Article 9 and Article 10, and Sections 2.6.1, 2.6.2, 2.7, 2.9, 2.12, 3.1.3, 3.1.5, 3.1.6, 3.1.9, 3.2 (solely to the extent addressing termination by Pfizer pursuant to Section 8.3.1), 3.6, 5.7, 5.8, 5.9, 5.10, 5.11, 5.12 and 5.13, shall survive any expiration or termination of this Agreement.

Pfizer Indemnity Obligations. Pfizer agrees to defend Arvinas, its Affiliates and their respective directors, officers, employees and agents (collectively, the “Arvinas Indemnitees”), and shall indemnify and hold harmless the Arvinas Indemnitees, from and against any liabilities, losses, costs, damages, fees or expenses payable to a Third Party, and reasonable attorney’s fees and other legal expenses with respect thereto, arising out of any claim, action, lawsuit, or other proceeding (collectively, “Losses and Claims”) brought against any Arvinas Indemnitee by a Third Party to the extent resulting from or relating to: (a) the manufacture, use, handling,

Arvinas Indemnity Obligations. Arvinas agrees to defend Pfizer, its relevant Related Parties and their respective directors, officers, employees and agents (collectively, the “Pfizer Indemnitees”), and shall indemnify and hold harmless the Pfizer Indemnitees, from and against any Losses and Claims brought against any Pfizer Indemnitee by a Third Party to the extent resulting from or relating to: (a) any personal injury claims arising in the course of the performance by Arvinas, its Affiliates or its subcontractors of its activities under the Research Program, (b) any breach by Arvinas of any of its representations, warranties or obligations pursuant to this Agreement, or (c) the gross negligence or willful misconduct of any Arvinas Indemnitee.

Procedure. If any Arvinas Indemnitee or Pfizer Indemnitee (each, an “Indemnitee”) intends to claim indemnification under this Article 9, the Indemnitee shall promptly notify the other Party (the “Indemnitor”) of any Losses and Claims for which the Indemnitee intends to claim such indemnification, and the Indemnitor shall assume the defense thereof with counsel selected by the Indemnitor and reasonably acceptable to the Indemnitee, provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitee (and, for clarity, not to be included in Losses and Claims), if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other Party represented by such counsel in such proceedings. The Indemnitor shall have the right to settle or compromise any claims for which it is providing indemnification under this Article 9, provided that the consent of the Indemnitee (which shall not be unreasonably withheld or delayed) shall be required in the event any such settlement or compromise would adversely affect the interests of the Indemnitee. The indemnity agreement in this Article 9 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to the Indemnitor’s ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 9, but the omission so to deliver notice to the Indemnitor shall not relieve it of any liability that it may have to any Indemnitee otherwise than under this Article 9. The Indemnitee under this Article 9, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification.

Limitation of Liability. Neither Party hereto shall be liable for indirect, incidental, consequential, special, exemplary, punitive or multiple damages arising in connection with this Agreement or the exercise of its rights hereunder, or for lost profits arising from or relating to any breach of this Agreement, regardless of any notice of such damages, provided, however, that this Section 9.4 shall not limit or restrict (i) damages available for breaches of confidentiality obligations Article 4 or (ii) the indemnification obligations of either Party pursuant to this Article 9.

Insurance. Each Party warrants that it maintains a policy or program of insurance or self-insurance at levels sufficient to support the indemnification obligations assumed herein. Upon request, a Party shall provide evidence of such insurance.

Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, potentially including embargoes, war, acts of war (whether war be declared or not), acts of terrorism, insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, or other acts of God, or acts, omissions or delays in acting by any governmental authority or the other Party. The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances.

Assignment.

Except as provided in this Section10.2, this Agreement may not be assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or transferred, by either Party without the consent of the other Party. Any attempted assignment not in accordance with this Section 10.2 shall be void. Any permitted assignee shall assume all assigned obligations of its assignor under this Agreement.

Pfizer may, without consent of Arvinas, assign this Agreement and its rights and obligations hereunder in whole or in part to an Affiliate of Pfizer or to the successor party in connection with a Change of Control. Arvinas may, without consent of Pfizer, assign this Agreement in its entirety to the successor party in connection with a Change of Control. Each Party agrees that, notwithstanding any provisions of this Agreement to the contrary, in the event that this Agreement is assigned by a Party in connection with a Change of Control, such assignment shall not provide the non-assigning Party with rights or access to independently owned or acquired intellectual property or technology of the acquirer of the assigning Party.

Use of Affiliates. Pfizer shall have the right to exercise its rights and perform its obligations under this Agreement either itself or through any of its Affiliates, provided that Pfizer shall at all times remain liable for the actions or inactions of any such Affiliate.

Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. The Parties shall in such an instance use reasonable efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

Dispute Resolution.

The Parties shall seek to settle amicably any and all disputes or differences arising out of or in connection with this Agreement. Any dispute between the Parties shall be promptly presented to the Chief Executive Officer of Arvinas and the President, Research and Development of Pfizer (or the equivalent position), or their respective designees, for

If the Parties do not fully settle any dispute between the Parties arising out of or relating to the validity or interpretation of, compliance with, breach or alleged breach of or termination of this Agreement pursuant to Section 10.7.1 within [**] of presentation to the senior officers for resolution as set forth therein, and either Party wishes to pursue the matter, each such dispute, controversy or claim that is not an “Excluded Claim” (as defined below) shall be finally resolved by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”), and as further provided below, and judgment on the arbitration award may be entered in any court having jurisdiction thereof.

The arbitration shall be conducted by a panel of three persons experienced in the pharmaceutical business. Within [**] after initiation of arbitration, each Party shall select one person to act as arbitrator and the two Party-selected arbitrators shall select a third arbitrator within [**] of their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the AAA. The arbitrators shall have scientific and legal experience relevant to the subject matter of the dispute. In any case the arbitrator shall not be a current or former Affiliate, employee, consultant, officer, director or stockholder of either Party, or otherwise have any current or previous relationship with either Party or their respective Affiliates. The place of arbitration shall be New York, New York, and all proceedings and communications shall be in English.

Within [**] after the designation of the arbitrators, the arbitrators and the Parties shall meet, and each Party shall provide to the arbitrator a written summary of all disputed issues, such Party’s position on such disputed issues and such Party’s proposed ruling on the merits of each such issue.

The arbitrator shall set a date for a hearing, which shall be no later than [**] after the submission of written proposals pursuant to Section 10.7.4, for the presentation of evidence and legal argument concerning each of the issues identified by the Parties. The Parties shall have the right to be represented by counsel. Except as provided herein, the arbitration shall be governed by the Commercial Arbitration Rules of the AAA applicable at the time of the notice of arbitration pursuant to Section 10.7.2); provided, however, that the Federal Rules of Evidence shall apply with regard to the admissibility of evidence in such hearing. In any such arbitration proceeding, the Parties shall be entitled to all remedies to which they would be entitled in a United States District Court and to full discovery to the same degree permitted under the Federal Rules of Civil Procedure.

The arbitrators shall use best efforts to rule on each disputed issue within [**] after completion of the hearing described in Section 10.7.5 The determination of the arbitrators as to the resolution of any dispute shall be binding and conclusive upon all Parties. All rulings of the arbitrators shall be in writing and shall be delivered to the Parties except to the extent that the Commercial Arbitration Rules of the AAA provide otherwise. Nothing contained herein shall be construed to permit the arbitrator to award punitive, exemplary or any similar damages. The arbitrator shall render a “reasoned decision” within the meaning of the Commercial Arbitration Rules, which shall include findings of fact and conclusions of law.

The (i) attorneys’ fees of the Parties in any arbitration, (ii) fees of the arbitrator and (iii) costs and expenses of the arbitration shall be borne by the Parties in a proportion determined by the arbitrator.

Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving any remedy under this Agreement or violating this Section 10.7, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party. The arbitrators shall have no authority to award punitive or any other type of damages excluded under Section 9.4.

Except to the extent necessary to confirm an award or as may be required by applicable Laws, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable statute of limitations.

The Parties agree that any payments made pursuant to this Agreement pending resolution of any dispute hereunder shall be promptly refunded if an arbitrator or court determines that such payments are not due.

As used in this Section, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (a) the validity or infringement of a patent, trademark or copyright; or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory.

Neither Arvinas nor Pfizer shall have the authority to make any statements, representations or commitments of any kind, or to take any action, which shall be binding on the other Party, without the prior written consent of the other Party.

Waiver. The waiver by either Party hereto of any right hereunder, or of any failure of the other Party to perform, or of any breach by the other Party, shall not be deemed a waiver of any other right hereunder or of any other breach by or failure of such other Party whether of a similar nature or otherwise.

Cumulative Remedies. No remedy referred to in this Agreement is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to in this Agreement or otherwise available under applicable Laws.

Business Day Requirements. In the event that any notice or other action or omission is required to be taken by a Party under this Agreement on a day that is not a business day (excluding notices required under Section3.7), then such notice or other action or omission shall be deemed to be required to be taken on the next occurring business day.

Further Assurances. Each Party agrees to do and perform all such further acts and things and shall execute and deliver such other agreements, certificates, instruments and documents reasonably necessary in order to carry out the mutual intent and accomplish the purposes of this Agreement and, at the other Party’s reasonable request and expense, to evidence, perfect or otherwise confirm such other Party’s rights hereunder.

Counterparts. This Agreement may be signed in any number of counterparts (including by facsimile or electronic transmission), each of which shall be deemed an original, but all of which shall constitute one and the same instrument.
